difficulties in the matter of providin a standard equipment which may be app ied to different types of cars without the necessity for desi ing a special construction for each car.

18 1s particularly the case with the installation ofthe brake cylinder and its connection to the brake rod.

The principal object of my invention is to provide a motor vehicle brake cylinder construction which may be generally applied without requiring changes in the construc tion in order to adapt same to diflerent designs of cars.

In the accompanying drawing; Fig. 1 is a central horizontal sectional view of a brake cylinder construction embodying my invention; and F ig. 2 a face view thereof.

- cylinder may be of prising aoasing plied to and released from. the diaphragm- As shown in the drawings, the brake the diaphragm type comformed of two sections 1 and 2 secured together'by bolts 3. Within the casing is'mounted a flexible diaphragm 4 having centrally secured thereto a rod 5 and having the diaphragm chamber 6 at the opposite side connected to a pipe '7 through which fluid under pressure is sup chamber,

Integral with the casing half section 2 is ,a bracket 8 having suitable" bolt holes for bolts 9, by which the bracket is secured to the car, the bracket being shown as bolted to the car frame 10 underneath the usual apron 11 which extends from the body to the running board 12 of the car. The securing face 13 of the bracket 8 is prefer ably at a slight angle to the axis of the brake cylinder, so as to permit the installation of a brake cylinder of somewhat greater diameter than; the space between-the body and the running board would otherwise allow. Mounted in suitable hearings in the bracket 8 is a rock shaft .14: having a squared portion intermediate the bearings and a squared portion extending outwardly from one of the bearings Secured to the central squared portion of the shaft 14 is an arm 15, the outer end of which is pivotally mounted in a clevis 16 secured to the rod 5.

On the extended squared portion of the shaft 14 and adjustable arm 17 is secured, the outer end of the arm being pivotally connected to the brake. rod 18. The arm 17 may be adjused laterally on the shaft 14 to suitdifierent positions of the brake rod 18 and may also be applied in diiierent angular positions, such as the position shown in full lines in Fig. 2 and the position shown in dotted lines in Fig. 1. The arm 17 may be provided in varying lengths, so that an arm suitable for a particular installation that the brake rod can be directly connected to the diaphragm rod 5.

Having now describedmy invention what I claim as new and desire to secure by Letters Patent, is A A fluid pressure brake cylinder for motor vehicles comprising a casing, a flexible diaphragm mounted in said casing, a bracket carried by the casing, a rock shaftmiounted in-said bracket, an arm secured to said shaft and operatively connected to said diaphragm, an adjustable arm adapted to be secured to said shaft in different angular positions, and a brake rod connected to'the last mentioned arm.

In testimony whereof I have hereunto set my hand; I
